Chemical Structure

(1S)-1-(2-methoxy-5-methylphenyl)ethanol CAS 156597-62-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 166.22 g/mol gives (1S)-1-(2-methoxy-5-methylphenyl)ethanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(1S)-1-(2-methoxy-5-methylphenyl)ethanol (CAS 156597-62-5), molecular formula C10H14O2 and molecular weight 166.22 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (1S)-1-(2-methoxy-5-methylphenyl)ethanol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
